"Come on, let me try again. What's going on?" Tang Yu murmured, and then he threw out a piece of flint and floated slowly towards the front.

In an instant, he felt that the flint appeared on his own territory. The slow-moving gear set turned rapidly. The speed was as fast as lightning. No, the lightning couldn't match its speed. At least, Tang Yu could catch his track. But when the gear set was running, there was no trace.

But at this time, Tang Yu was surprised to find that in the air, countless air was absorbed into the shrinking device in an instant, but in an instant, it was ejected out.

"Boom

"Click

Tang Yu couldn't help frowning. This time, the air cannon didn't have the same power as before. When it hit the yihuoshi, it didn't explode at once. It just "Chuchi" and fell to the ground without any cracks.

"This It won't happen just because I broke the wall Tang Yumu gaped.

After the corner of the eye, I suddenly noticed that there was a fast flowing golden light on the rotating gear set.

"Bang

I don't know if it was an illusion. Tang Yu felt that there was something wrong with the rotation of the gear set.

"Bang!"

Then, in less than two seconds, the gear set exploded directly in Tang Yu's shocked eyes. In an instant, the 100 meter long gear set turned into pieces.

"I don't seem to have done anything!" Tang Yu was even more angry with his eyes and tongue tied. He thought that the gear set was still interesting. He felt that he could not destroy a small flint, so he committed suicide with guilt?

Of course, Tang Yu also knows that this is just a joke! There must be something wrong with this gear set.

However, if there is something wrong, it should be one side of the problem. Why are problems on both sides now? Tang Yu's eyes were on his left side again. The wall which was also torn apart was also damaged.

What's more, the damage is quite thorough. Except for a pile of powder of gears, even a trace can't be seen.

"I just want to see what's going on. Do you want to have such a pit?" Tang Yu was extremely depressed. Although he said that this kind of air cannon device had no effect on him, the problem was that he could not solve what he wanted to know.

Tang Yu's eyes looked ahead. There was still a 800 meter long corridor. In the air, there was still a faint sound of gear turning.

Tang Yu bit his teeth and muttered, "I don't believe it if there are still 800 meters left. There should be eight pairs of gear sets here, so I can't find a secret!"

"Hum!"

Tang Yu raised his feet and walked forward until he reached the end of the damaged gear set where the air cannon was ejected. Tang Yu stopped and looked at the walls on both sides.

This time, the holes on the walls on both sides changed again.

There are not many holes in this section of the wall, but there is still one every 20 cm. There are about two adults of all sizes. The holes on both sides of the wall show a cross situation and are arranged.

In other words, there will be an attack every ten centimeters.

Old rules, Tang Yu threw out a piece of industry flint.

Maybe it's because the person who made this gear set is the same! When the flint floats to 10 meters away, there is a "boom" sound in the whole corridor, and purple and blue flames are ejected from the holes.

"Boom!"

In an instant, the 100 meter long corridor was filled with this kind of flame, and there was no dead corner left.

After less than 10 seconds of burning, the flint is directly dissolved, a little melting, but before the molten flint drops to the ground, it is directly roasted and dissipated by the flame.

"This kind of machine should be a mechanism." Tang Yu hesitated and said slowly.

"This kind of mechanism is very powerful." Tang Yu sighed with emotion. He felt that the arrangement of this kind of organ could indeed be regarded as the existence of hanging and blasting the sky.

At least, the organs he met before may be more delicate, but the problem is that they are not as powerful as those in front of him.

"This one horned man is also a cow!" Tang Yu admired him very much.

No matter what you admire or not!

Tang Yu hit the wall with one blow. This time, he did not go to explore the situation of this kind of flame. He directly broke the wall and exposed the gear set inside.

This piece of wall also appears to be relatively fragile. Tang Yu's one punch directly broke the wall and exposed the gear set inside.

This gear set is not as tough as the gear set in front of it. When Tang Yu broke the wall, it also directly put out the fire. In an instant, six gears burst to pieces, making the whole gear set stop working."Hum!"

After a roar, there was no spark in the corridor.

"The intensity is not good!" Tang Yu, like an old man, frowned and commented on the mechanism in front of him. "Although it is said that the damage caused by the fire is indeed there, it is too hard to bear the blow. It can't be done. It needs to be corrected."

Tang Yu murmured that he was ready to move on. However, at this time, he suddenly noticed that the flame spraying gears were different from the ones before. The former kind of gears gave people the feeling that they were simple but ordinary. Now, although they are also simple, they are absolutely extraordinary. Each gear is carved with patterns that Tang Yu can't understand These patterns are a little similar to the runes, but they have no similarities with the various runes and Longwen that Tang Yu studied before.

"Is this a new rune?" Tang Yu murmured in a low voice, with a trace of interest. He pulled a complete gear from the wall, held it in his hand, and looked at it carefully.

This gear is not very big. It is only the size of an adult's palm. Tang Yu can easily nest in his hands.

Tang Yu, who had studied many kinds of runes and Longwen, studied the patterns on the gear and finally came to two conclusions: either this kind of rune is described in the special characters of the unicorn people, or the pattern is not a rune, but a ghost symbol!

That's right!

Tang Yu regarded this kind of thing as ghost symbol.

He also had no way, because these lines, really have no rules, are completely like the things that people pinch.

"Forget it! I'll talk about it later! Let's finish exploring the mechanism array in this corridor first Tang Yu put the gear into the ring, and then went on.

Tang Yu has now discovered the role of three gear sets, that is to say, three mechanism arrays have been found.

At the back, there are still 700 meters. I don't know if it is true that a new mechanism array appears every 100 meters. If so, it means that there are still seven gear sets in the corridor.

Tang Yu took a deep breath and groped down.

In the next seven hundred meters, Tang Yu experienced not seven gear sets, but fourteen gear sets. In other words, an average of 50 meters was a gear set. Each of these gear sets must have different effects, toxic, gas, and even defensive in addition to attacking.

However, at most, the wall of basi mountain was broken by Tang Yu's five fists. Either it directly broke the gear, or it had its own problems, and then it burst into pieces, allowing Tang Yu to finally pass through the 1-kilometer long corridor.

After passing through the corridor, Tang Yu suddenly realized that the corridor was like
